I cannot fully explain all aspects of the movie easily and clearly in a text smaller than a large volume, but yet I will try to compress it decently here. First and foremost, the movie for me is like a spectacle which could go on with the same cast for 100 hours and still be interesting and captivating. I have always wished it had been a series with this cast instead of a movie. Futile wishes!
The casting, to begin with, is very well matched to the book's spirit if not the physical descriptions. Vivien Leigh, Clark Gable, Olivia de Havilland and Hattie McDaniel. I stop here and will edit it bit by bit to complete it in a few days. It is too large to finish in one writing.
